"Token used before issued"

When running Go program on my mac, I am receiving the following error when parsing a JWT: "Token used before issued".

However, when I am running on a remote server it is working fine. What causes this issue and how can I resolve it?

EDIT: strangely, a reboot of my macbook resolved the issue. It had never occurred before. Any idea what might have caused this issue? I tried changing my Mac system timezone to UTC but it didn't resolve it either.
